Abstract

Proceso para estabilización de compuestos antioxidantes caracterizado por el hecho de comprender la etapa de conectar dicho compuesto, en un medio acuoso, con un compuesto desoxigenador, un compuesto secuestrador de iones metálicos y un compuesto de reversión de oxidación de reacción. Proceso de acuerdo con la reivindicación 1, caracterizado por el hecho de que el compuesto antioxidante es seleccionado del grupo comprendido el ácido ascórbico levórgiro (LAA) y proantocianidinas (OPCAND#39S.) Proceso de acuerdo con cualquier una de las reivindicaciones 1 y 2, caracterizado por el hecho del antioxidante ser LAA . Proceso de acuerdo con las reivindicaciones 1 a 3, caracterizado por el hecho del antioxidante comprender aún proantocianidinas (OPCAND#39s). 2Composición acuosa de acuerdo con la reivindicación 20, caracterizada por el hecho de que el compuesto desoxigenador es elegido entre propilenoglicol, butilenoglicol y sus mixturas, con mayor preferencia siendo propilenoglicol. 2Composición acuosa de acuerdo con cualquier una de las reivindicaciones anteriores, caracterizada por el hecho de que el compuesto secuestrador de iones metálicos es seleccionado del grupo comprendiendo ácidos etilenofosfónicos, sus sales y sus mixturas o del grupo que comprende los fosfonatos que incluyen ácidos di-, tri-, tetra- y pentavalentes, sus sales y sus mezclas. <EMI FILE="00053359_1" ID="1" IMF=JPEG >Process for stabilizing antioxidant compounds characterized by understanding the step of connecting said compound, in an aqueous medium, with a deoxygenating compound, a metal ion sequestration compound and a reaction oxidation reversal compound. Process according to claim 1, characterized in that the antioxidant compound is selected from the group comprised of ascorbic acid levórgiro (LAA) and proanthocyanidins (OPCAND # 39S.) Process according to any one of claims 1 and 2, characterized by the fact of the antioxidant being LAA. Process according to claims 1 to 3, characterized in that the antioxidant still comprises proanthocyanidins (OPCAND # 39s). Aqueous composition according to claim 20, characterized in that the deoxygenator compound is chosen from propylene glycol, butylene glycol and mixtures thereof, more preferably propylene glycol. Aqueous composition according to any one of the preceding claims, characterized in that the metal ion sequestering compound is selected from the group comprising ethylene phosphonic acids, their salts and mixtures thereof or from the group comprising phosphonates that include di-, tri-, tetra- and pentavalent, their salts and mixtures. <EMI FILE = "00053359_1" ID = "1" MFI = JPEG>
